In order to boost her flagging popularity, former idol group singer Oh In-young (Kim Dasom) agrees to appear in a television reality show that pairs up fake mothers- and daughters-in-law. In-young\'s partner is Yang Choon-ja (Go Doo-shim), the matriarch of a long-standing traditional clan, and they end up hating each other on the show. But as fate would have it, the two later end up becoming mother and daughter-in-law for real.
